Objective To explore the impact of number of positive regional lymph nodes (nPRLN) in N1 stage on the prognosis of non-small cell lung cancer (NSCLC) patients. Methods Patients with TxN1M0 stage NSCLC who underwent lobectomy and mediastinal lymph node dissection from 2010 to 2015 were screened from SEER database (17 Regs, 2022nov sub). The optimal cutoff value of nPRLN was determined using X-tile software, and patients were divided into 2 groups according to the cutoff value: a nPRLN≤optimal cutoff group and a nPRLN>optimal cutoff group. The influence of confounding factors was minimized by propensity score matching (PSM) at a ratio of 1 : 1. Kaplan-Meier curves and Cox proportional hazards models were used to evaluate overall survival (OS) and lung cancer-specific survival (LCSS) of patients. Results A total of 1316 patients with TxN1M0 stage NSCLC were included, including 662 males and 654 females, with a median age of 67 (60, 73) years. The optimal cutoff value of nPRLN was 3, with 1165 patients in the nPRLN≤3 group and 151 patients in the nPRLN>3 group. After PSM, there were 138 patients in each group. Regardless of before or after PSM, OS and LCSS of patients in the nPRLN≤3 group were superior to those in the nPRLN>3 group (P<0.001). N1 stage nPRLN>3 was an independent prognostic risk factor for OS [HR=1.52, 95%CI (1.22, 1.89), P<0.001] and LCSS [HR=1.72, 95%CI (1.36, 2.18), P<0.001]. Conclusion N1 stage nPRLN>3 is an independent prognostic risk factor for NSCLC patients in TxN1M0 stage, which may provide new evidence for future revision of TNM staging N1 stage subclassification.

Objective To investigate the epidemiological characteristics, influencing factors, and community dietary network drivers of clonorchiasis in Longjiang Village, Congjiang County, Guizhou Province using social network analysis from a One Health perspective, so as to provide insights into implementation of precision control measures. Methods Longjiang Village, Congjiang County, Guizhou Province was selected as a survey point. A total of 128 permanent residents at ages of over 6 years were sampled using a random sampling method, and subjects’ stool samples were collected. In addition, at least 10 fecal samples were collected from domestic cats and dogs, reservoir hosts of Clonorchis sinensis, and at least 80 freshwater snails and at least 200 freshwater fish, intermediate hosts of C. sinensis, were sampled in Longjiang Village. C. sinensis eggs were detected in human, domestic cat and domestic dog fecal samples using a modified Kato-Katz thick smear method (two slides for one stool sample) . The C. sinensis metacercariae were detected in freshwater fish with a compression method and the C. sinensis cercariae were detected in freshwater snails with a cercarial shedding method, respectively. Participants’ demographic characteristics, dietary and drinking hygiene behaviors and food-sharing relationships were collected with structured questionnaires and semi-structured in-depth interviews, and factors affecting C. sinensis infection were identified using regression analysis. Based on the north-south orientation delineated by the village river, participants were divided into groups a and b. Subjects’ food-sharing network was analyzed using social network analysis, and the Louvain algorithm was employed to investigate the community structure and key nodes of the network. Results The overall prevalence of C. sinensis infection was 33.59% (43/128) among participants in Longjiang Village, Congjiang County, Guizhou Province. The detection of C. sinensis metacercariae was 7.63% (22/288) in freshwater fish, and no C. sinensis cercariae were detected in freshwater snails. The prevalence of C. sinensis infection was 7.69% (1/13) in domestic cats, and no infection was detected in domestic dogs. Regression analysis identified age groups of 25 to 45 years [adjusted odds ratio (AOR) = 23.17, 95% confidence interval (CI): (1.85, 490.29)], Dong ethnicity [AOR = 26.80, 95% CI: (1.54, 1 105.09)], frequent consumption of raw water [AOR = 9.39, 95% CI: (1.58, 99.79)], and consumption of raw fish [AOR = 3.49, 95% CI: (1.52, 34.69)] as independent risk factors for C. sinensis infection among villagers in Longjiang Village (all P values < 0.05). Social network analysis showed a significantly higher global clustering coefficient (0.52 vs. 0.16; t = 2.41, P = 0.02) and average local clustering coefficient (0.52 vs. 0.16; t = 2.41, P = 0.02) in Group b than in Group a, and a significantly higher degree centrality was found among C. sinensis-infected individuals than among uninfected individuals in Group b (17.54 vs. 4.26; t = 2.33, P = 0.02). There was a high-risk community S11 with a 45.83% prevalence rate of C. sinensis infection in Group b, and C. sinensis-infected individuals with high betweenness centrality in Group b might serve as critical “bridges” in the food-sharing network, which facilitated the aggregation and diffusion of the risk of C. sinensis infection in the community. Conclusions Individual dietary behaviors, such as drinking raw water and consuming raw or undercooked fish, and sociocultural factors of household-neighborhood food-sharing networks, may contribute to the clustering transmission of clonorchiasis in Longjiang Village. The clonorchiasis control strategy is recommended to shift from individual-centered health education towards integrated interventions under a One Health framework in this region, which focus on key individuals within social networks, strengthen coordinated water and environmental management, and enhance community participation to improve the acceptability and sustainability of interventions.

Objective To simulate modern social stress using a pre-pregnancy chronic mild stress(CMS)model and to explore the mechanisms of emotional,behavioral,and neurodevelopmental changes in male offspring of pre-pregnancy liver qi stagnation female mice through corticosterone(CORT)-brain-derived neurotrophic factor(BDNF)extracellular signal-regulated kinase(ERK)1/2 signaling cascade-mediated hippocampal injury.This study aimed to elucidate the impact of negative life events on offspring and the interventional mechanism of Shuyu Capsules.Methods CMS stress was used to induce pre-pregnancy depression in female rats(liver qi stagnation state),followed by intervention with Shuyu and fluoxetine capsules.After screening,male rats were mated and 12 male offspring from each group were selected for behavioral testing and detection of serum CORT levels by enzyme-linked immunosorbent assay.BDNF,ERK1/2,phospho(p)-ERK1/2,cAMP-response element binding protein(CREB),and p-CREB protein levels in the hippocampus were detected by Western Blot,and BDNF,ERK1,ERK2,and CREB mRNA levels in the hippocampus were detected by reverse transcription-polymerase chain reaction(RT-PCR),to verify the effects of pre-pregnancy CMS on the BDNF-ERK1/2-CREB signaling pathway and to investigate the key micro-mechanisms of Shuyu Capsules on emotional and learning memory-related behaviors of male offspring of females with pre-pregnancy liver qi stagnation syndrome.Results The distance,number of entries,and duration of stay in the central area in open-field experiments were significantly reduced in offspring in the model group(all P<0.05).The escape latency during the exploration period of the water-maze experiment was significantly prolonged(P<0.05)and the swimming distance,duration of the target quadrant,and number of platform crossings were significantly reduced(P<0.05,P<0.05,P<0.01),the suspension time and frequency in the forced-swimming experiment were increased(P<0.05,P<0.01),and the incubation period was shortened(P<0.05)in offspring in the model group.Prophylactic treatment with Shuyu Capsules and fluoxetine improved the depression-like behavior and cognitive impairment in the offspring in the model group.Biochemical tests showed that CORT levels were increased in the CMS model group(P<0.05),BDNF,p-ERK1/2,and p-CREB protein levels in the hippocampus were decreased(all P<0.05),and BDNF,ERK1,ERK2,and CREB mRNA levels were significantly reduced(P<0.01,P<0.05,P<0.01,P<0.05).Treatment with Shuyu Capsules and fluoxetine increased the CORT content and BDNF,ERK1/2,and CREB protein and mRNA levels in male offspring to varying degrees.Conclusions High levels of CORT in offspring act selectively on the hippocampus,exerting adverse effects on the emotional and learning memory functions of rats by downregulating the BDNF-ERK1/2 signaling cascade.The Chinese medicine Shuyu Capsules can reduce the impact of an adverse intrauterine environment on offspring development by correcting abnormal levels and pathways of glucocorticoids.
